C#轻量级写文本日志

## 调用

```csharp
            var filePath = "logs/" + DateTime.Now.ToString("yyyyMMdd") + ".log";
            //添加日志记录
            DoIOFile.Write(filePath, "项目启动了" );
```

## 方法

```csharp
                /// <summary>
        /// 创建文件或者附加内容
        /// </summary>
        /// <param name="Data">要写入的文本</param>
        /// <param name="Encode">编码方式</param>
        /// <param name="filePath">文件路径(支持相对路径或绝对路径)</param>
        /// <param name="IsAppend">附加还是全新写入</param>
        public static bool Write(string Data, string filePath="", bool IsAppend = true, string Encode = "UTF-8")
        {
            filePath = string.IsNullOrEmpty(filePath) ? "logs/" + DateTime.Now.ToString("yyyyMMdd") + ".log" : Encode;
            Encode = string.IsNullOrEmpty(Encode) ? "UTF-8" : Encode;
            Data = DateTime.Now.ToString()+"  :"  + Data + "\n";
            try
            {
                //获取文件对象
                FileInfo file = new FileInfo(filePath);
                //判断文件夹是否创建
                if (!file.Directory.Exists) { file.Directory.Create(); }
                //判断文件是否存在
                //或者判断文件属性是否只读,是只读的话将只读属性去掉
                if (!file.Exists) { using (file.Create()) { } }
                else if (file.Attributes.ToString().IndexOf("ReadOnly") != -1) { file.IsReadOnly = false; }
                //将内容覆盖或者追加到文件的最后
                using (StreamWriter writer = new StreamWriter(file.FullName, IsAppend, Encoding.GetEncoding(Encode)))
                {
                    writer.Write(Data);
                    writer.Flush();
                }
                return true;
            }
            catch (Exception ex)
            {
                Console.Write(ex.Message);
                return false;
            }
        }
